APAR Error Description / Circumvention

-----------------------------------------------
When operating in Geographic Mirroring while in Asynchronous
Delivery Mode, there is a potential for overwhelming the
communications
network which can cause a suspend due to a timeout of an
operation.

MSGCPI096F is a common error message that will get posted to the
QSYSOPR message queue when Geographic Mirror Suspends. Not all
cases of Suspend will be addressed by this enhancement, but for
environments that are mirroring a lot of data and the network is
not fully capable of handling the max load, the enhancement will
prove to be beneficial.

CORRECTION FOR APAR MA42570 :
-----------------------------
Geographic Mirroring while in Asynchronous Delivery Mode will
better pace operations such that those operations are less
likely to overwhelm the communications network.

CIRCUMVENTION FOR APAR MA42570 :
--------------------------------
None.
